첨가제로 $Al_{2}$$O_{3}$가 포함된 ZnO 소결체가 타깃을 이용하여 RF 마그네트론 스퍼터링법으로 Al이 첨가된 ZnO박막을 증착하고, 타깃에 첨가된 $Al_{2}$$O_{3}$의 농도와 증착시 스퍼터링장치내의 기판위치에 따른 박막의 물성 변화를 고찰하였다. 타깃의 $Al_{2}$$O_{3}$ 첨가농도가 2wt%인 경우에 비저항치 8 $\times$ $10_{-3}$ $\Omega$-cm인 박막이 증차되었다. 또한 $Al_{2}$$O_{3}$가 2wt%이상 첨가된 경우는 모든 Al이 박막내부에서 Zn를 치환하여 전자주게로의 역할을 하지 못하고, 오히려 치환되지 못한 Al원자의 중성 불순물 산란효과에 의해 박막의 비저항이 증가하였다. 타깃의 마모영역 위에서 증착된 Al을 첨가한 ZnO 박막은 그 영역 KR에서 증착된 박막보다 높은 비저항값을 나타냈으며, 이는 큰 에너지를 가지는 산소입자의 충돌에 기인한 것으로 여겨진다.

Although the most commonly encountered orbital tumor is metastatic tumor, adenocarcinoma of stomach metastasized to the optic nerve is rarely reported. The authors discuss a rare case of metastatic adenocarcinoma of left optic nerve with a review of literature. A 44-year-old man presented with decreased visual acuity of left eye for 3 months. Neurologic examination revealed left optic neuropathy. On MR imaging, a homogenously wellenhanced mass surrounding left optic nerve around optic canal was noticed. The X-rays and the whole body bone scan sho-wed multiple bony metastasis. Subtotal removal was performed via combined subfrontal and pterional approach and metastatic adenocarcinoma from the stomach was confirmed histologically. Postoperative course was uneventful, but there was no improvement of visual acuity.

Product liability is the law of the manufacturer's responsibilities for the consumers' personal injuries or the losses of property resulted from defective products. In today's many countries, the product liability law are being enacted because of the safety of product use and the protection of consumer's right. In korea, the product liability is going to enforce on July 1, 2002. Though the construction of product liability response system is urgent situation, domestic manufacture company's PL response system is not nearly prepared in present. Consequently, the purpose of this study is to discuss the Quality Management's importance and the PL countermeasures by presenting the difference of PL response system construction degree by the Quality Management Maturity degree

본 연구에서는 규불화염, 가용성 실리카, 방향족계 고분자 축합물 그리고 잠열특성을 지닌 질산염계 무기화합물로 구성된 규불화염계 수화열 저감제를 시멘트 모르타르의 수화열 및 건조수축에 미치는 영향을 조사하였다. 규불화염계 수화열 저감제의 첨가로 시멘트 모르타르의 단열상승온도 및 건조수축에 의한 길이변화가 저감되는 특성을 나타내었다. 또한, 규불화염계 수화열 저감제가 첨가된 판상형 시멘트 모르타르 시험체의 균열 패턴을 측정한 결과, 수화열 저감과 건조수축에 의해 길이변화가 저감되는 복합적 효과를 통해 시멘트 모르타르의 균열저감성이 개선되는 것을 확인하였다. Fluosilicate salts based hydration heat reducer(SWP-HR), used in this study, is composed of fluosilicate salts, soluble silica, aromatic polymer condensate and nitrate salt based inorganic compound with latent heat property. Effects of SWP-HR addition on the hydration heat and anti-crack property of cement mortar were investigated. Adiabatic hydration temperature and drying shrinkage length of SWP-HR added cement mortar had a tendency to decrease compared to those of cement mortar without SWP-HR addition. Also, it was confirmed through crack pattern experiment of plate-form specimen for elucidating crack-reducing characteristic that anti-crack property of SWP-HR added cement mortar was improved.

Objectives: This study was performed to assess the comorbidity and associated emotional and behavioral manifestations in attention deficit hyperactivity disorder(ADHD) subjects, and the parenting stress and sense of competence in their mothers. Method: To investigate the comorbid conditions of ADHD, 102 ADHD patients(82 males, 9.58±2.65) and their caregivers visiting outpatient clinic were interviewed using the Korean version of Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime. The Korean-Child Behavior Checklist, Children`s Depression Inventory, and Revised Children`s Manifest Anxiety Scale(RCMAS) were used to measure the psychopathologies in the subjects. The Parenting Stress Index/Short form and Parenting Sense of Competence Scale were also applied to the caregivers of ADHD patients. Results: Eighty-four(82.4%) of ADHD subjects had comordid psychiatric disorders. Comorbid oppositional defiant disorder, anxiety disorders, tic disorders, and elimination disorders were accompanied with ADHD in 54.9%, 24.9%, 19.6%, and 12.7%, respectively. Mean scores of Social Problems, Total Behavior Problems, and RCMAS were significantly higher in comorbid ADHD group than pure ADHD group. Parents of ADHD patients with comorbidity reported higher parenting stress and lower parenting sense of competence. Conclusion: Majority of ADHD patients had comorbid psychiatric conditions, and more psychopathologies and related parenting complications were associated with comorbidity.

2017년 10월 개최된 제19차 중국공산당 전국대표대회에서 시진핑은 사이버 안보의 중요성을 피력하며, 사이버 강국을 향한 정보·통신기술의 발전을 집권 2기 우선순위로 삼았다. 실제 2018년 중국의 국가별 네트워크준비지수는 138개 국가 중 36위에 불과해, 중국이 인터넷 대국이지만, 사이버 강국이 아님을 만천하에 드러냈다. 그간 중국은 급속한 인터넷 발달에 맞물려 사이버공간의 내부 통제와 첩보활동에 방점을 두고 사이버 기술을 발전해온 결과, 국외로부터의 안보전략은 부재했다. 하지만 시진핑 집권 후 중국은 공세적인 도메인 확보와 자국 기술의 네트워크확산 정책을 펼침으로써, 전 세계 사이버 장악력 확대를 꾀하고 있다. 이런 배경에서 이 연구는 중국이 내부 인터넷 통제에서 외연을 확장해 사이버 안보에 천착하게 된 동인을 사이버 공간의 취약성 차원에서 규명했다. At the 19th National Congress of the Communist Party of China held in October 2017, Xi Jinping emphasized the importance of cyber security, presenting the advancement of information and communications technology as one of the priority policy tasks for his second term. Indeed, as of 2018, China ranked 36 out of 138 countries in the Network Readiness Index, and this demonstrates that although it is an Internet powerhouse, China is not as powerful as expected in terms of cyber security. In the meantime, the Chinese government has been developing cyber technologies focusing on cyberspace internal controls and espionage, along with the explosive growth and advancement of the Internet, but there has been no cyber strategy against external threats. Since President Xi took power, however, the country has been adopting aggressive policies to secure domains and spread networks based on its proprietary technologies, aiming to reinforce and expand its control over the cyber world across the globe. Ultimately, this paper examines what motivated the Chinese government to pursue an external extension from the internal controls of the Internet and to prioritize cyber security.
